Book Description:

Apache Solr: A Practical Approach to Enterprise Search teaches you how to build an enterprise search engine using Apache Solr. You’ll soon learn how to index and search your documents; ingest data from varied sources; pre-process, transform and enrich your data; and build the processing pipeline.

You will understand the concepts and internals of Apache Solr and tune the results for your client’s search needs. The book explains each essential concept―backed by practical and industry examples―to help you attain expert-level knowledge.

The book, which assumes a basic knowledge of Java, starts with an introduction to Solr, followed by steps to setting it up, indexing your first set of documents, and searching them. It then covers the end-to-end process of data ingestion from varied sources, pre-processing the data, transformation and enrichment of data, building the processing pipeline, query parsing, and scoring the document. It also teaches you how to make your system intelligent and able to learn through feedback loops.

After covering out-of-the-box features, Solr expert Dikshant Shahi dives into ways you can customize Solr for your business and its specific requirements, along with ways to plug in your own components.
